Abstract

There are many applications for high gain dc-dc converters. In several of these applications galvanic isolation is not required, but there are some safety issues regarding missing isolation and leakage current. Usage of a half-bridge inverter and a dual dc-link may solve this issues. In this paper very simple dual output non-isolated boost converter is presented. Single active switch is used to control both, positive and negative output voltages. The converter is desired to boost unregulated low input voltage 25-50 Vdc to regulated high voltage plusmn400 Vdc in dual dc-link. In this paper proposed topology is analyzed and explained. Obtained experimental results prove good performance of the converter over wide range of input voltage and output power.
